Picture of the day Willistead Manor

Willistead Manor is a historic house located in the former town of Walkerville, Ontario, now part of Windsor. Designed by Albert Kahn for Edward Chandler Walker and built between 1904 and 1906, the manor was ceded to the community in 1921, a few years after Walker's death. Having served as Walkerville's town hall, the Art Gallery of Windsor, and a branch of the Windsor Public Library, it is currently used as a banquet hall. The manor is designed in the Tudor Revival style, and the grounds also include a coach house and a gate house of similar design. This photograph shows the front facade of Willistead Manor in 2025.

Zhao Chongguo (137 BCE – 52 BCE) was a Chinese military commander and official during the Western Han dynasty. Emperor Wu, impressed by Zhao's military service, promoted him, and he served as chief of staff for the supreme head of cavalry units. In 74 BCE, Zhao collaborated with the political leader Huo Guang to depose the newly enthroned emperor Liu He in favor of Emperor Xuan. For this, he was appointed Marquis of Yingping and promoted to general of the rear. He volunteered to lead a campaign against the Qiang people in 62 BCE. Joined by his son, he persuaded the Qiang to defect to the Han cause. Zhao rejected proposals by his fellow generals and the Emperor to continue offensive operations, believing that a protracted occupation would subdue the Qiang through attrition. He was able to implement a policy of tuntian (establishing farming garrisons) in spite of imperial opposition. This gained him acclaim and influenced later strategists. He retired in 60 BCE after his son caused a scandal. (Full article...)
